Common cat ownership challenges

Having a or several cats in your home can mean unwanted side effects including but not limited to the following:

Dander, hair, fur causing breathing issues
Even if a cat’s hair is combed regularly fur, dander and fluff can still gather in your home and be present in the air in higher levels than home without a feline friend.
If left unmanaged this fur and hair can settle and collect in hard to clean locations, which mean more germs in your home or worse can float in the air only to be breathed in and giving extra work for your lung.
An air purifier can grab cat hair from the air of a room and filter it out before pumping new fresh air into the room.

Cat allergies
Cat allergies can come in various levels of severity and seriousness from mild irritation to causing breathing issues, skin conditions and sinus issues.
Some people with mild cat allergies have found that an air purifier can lessen the impact of their allergy and make living with a cat possible.
Depending on the severity of your pet allergy you may be able to medicate and use air treatment products to make life with a cat possible.
It make sense that an air purifier can help with cat allergies as dust specific pre-filters can catch cat hair from the air and mean less work for your lungs. Also purifiers can prevent the collection of cat hair which increase germ presence in a home.
This removal or limiting of germs can mean a decrease in symptoms of cat allergies like skin conditions or sneezing.

Smells – urine, litter tray, food etc.
It’s an unavoidable fact that cats mean new smells in a home. From urine and cat poop in kitty litter trays to pungent smells from cat foods.
These smells can be challenging from cat owners and if left unmanaged can reach all areas of your home.
Again, an air purifier can help via the use of an activated carbon filter which absorbs smells from rooms prior to air being cleaned.
These carbon filters are incredibly effective at capturing unwanted smells and can make the difference between a smelly home and one full of fresh clean smelling air.
This feature is particularly useful if you have multiple cats as smells will be magnified.
The trouble with cat ownership smells is if you are in your home a lot you become accustomed to the everyday smells and their impact become lessened.
However, when someone new comes into your home the smells can be quite strong!

Cat hair on clothes and fabrics
Even if cats have their fur cleaned and brushed regularly a certain amount of fur will molt and get onto clothes and fabrics around the home like sofas, throws, bedding and cushions.
If this hair is left to gather it will become a heaven for germs and become unclean.
Whilst an air purifier will not tackle hair which has already settled it will remove the car hair from a rooms air.
If you have an air purifier running when cleaning existing cat hair this will mean any cat hair which is disturbed during cleaning will be pushed into the air and then caught by the air purifier.

Skin irritation – washing hands frequently (after stroking cat)
Some cat owners find that they develop skin conditions from living with a cat either due to the cat itself or frequent washing of hands after stroking their cat.
Skin irritations are a tricky thing to live with as they affect you most of the day and can be painful if left untreated. Also, if left to develop can lead to more serious issues like infection.
Whilst an air purifier won’t directly solve skin irritation as a result of cat ownership, they will work to remove the cat hair from the air of your home which would have otherwise settled and result in a skin complaints.

So it’s clear to see that there are a number of ways which an air purifier can positively impact of cat ownership!

Living with multiple cats
People who love cats often have more than one and often lots of cats so they can keep each other company.
Living in a home with more than one cat in residence can present specific issues from more cat hair in the air and on fabrics around the house to extra smells from multiple litter trays and cat bowls.
Generally, in terms of air treatment, the advice for living with multiple cats is the same as living with one furry friend.
However, you may want to invest in a more powerful air purification device or multiple air purifiers so you can place units in different rooms around your home especially in areas which your cats commonly hang out in.


Cat allergies – reducing the impact

There are a number of ways the impact and symptoms of cat allergies can be reduced including frequent cleaning of your home to stay on top of levels of cat hair and dust, to restricting your cat’s access to certain areas of the home.

The below list presents some ideas for how to reduce the impact of cat or pet allergies in your home:

  • don’t allow your cats into the bedroom to reduce cat hair which is breathed in at night
  • regularly clean areas where cats sleep to keep cat hair levels to a minimum
  • frequently clean household fabrics, sofas, cushions and throws which can collect cat hair
  • dust on a weekly basis to reduce the level of dust and cat hair build up
  • brush your cat’s hair regularly to reduce the level of loose hair making its way into air of rooms
  • wipe down and clean feeding areas for cats on a frequent basis to limit build-up of food debris
  • change cat litter trays and sand regularly to avoid smells building and worsening


How a purifier can help with cat allergies

Purifiers can help with the common issues which come hand in hand with cat ownership in a number of ways including the following:

1. Work to improve air quality
By removing cat hair and smells from the air in the rooms of your home. Air is easy to breathe less labor intensive for your lungs to filter and your home will suffer from less smells.

2. Remove hair and fur from the air – especially after brushing
Purifiers will remove the dust and cat hair or fur which is currently in the air and overtime, reduce the amounts of cat hair which builds up over time. This will mean less cat hair is breathed in by people in your home and less cat hair settling and thus being allowed to collect pockets of germs and smells.
All with the pleasant benefit of a new supply of fresh clean air to breathe in!

3. Remove smells – litter, food and urine
There’s no two ways about it cats generate smells and an air purifier will reduce or remove the common smells which are part of cat ownership like kitty litter trays, urine, cat poop and strong cat food smells.
Using an air purifier fitted with a activated carbon filter will filter out smells from the air of your home which is a plus for those living in your home, visitors and your cats!

4. Less cat hair on clothes
Another downside to owning cats is getting cat hair and fur build up on your clothes. Using an air purifier to capture excess cat hair from a rooms air will ultimately mean less cat hair makes its way onto your clothes which means easier cleaning of clothes and less washing!


Purifier features to look for when choosing a purifier to tackle cat smells

When choosing an air purifier to tackle cat hair or smells you will need to look out for the following features:

Activated carbon or separate filter
Highly important when choosing a cat friendly air purifier as the carbon filter will be a key ally in the battle against cat smells.
Choosing a purifier which has a separate carbon pre-filter which remove dust and smells before air is passed through the Ture HEPA filter will help to extend the lifecycle of your main HEPA filter.

True HEPA filter
Only buy purifiers with True HEPA filters to be assured of quality and efficiency of the purifier unit.

Purifiers which use a true HEPA are the only devices that are certified to capture 99.97% of particles as small as 0.3 microns in size. This includes all types of dust particles and even dust mites, hair and airborne debris of all types.

Washable filters
Washable filter and pre filters are a great way to extend the life of your HEPA filter and can often mean higher efficiency in dealing with hair, dust and airborne debris.

You may want to move your purifier around the different rooms of your home so it important to choose a purifier which can easily be moved to different rooms and tackle cat smells or high levels of cat hair on a priority basis. If you choose a big bulky purifier which is difficult to move or even lift then it will only be able to clean the air of the room which it’s located in!
Most modern purifiers are light, small and very portable so can quickly be relocated to new rooms based on your changing needs!

Room capability CADR
Look for a purifier which boasts high CADR rating as this will mean the purifier can work quickly to change and cycle the air of the rooms in your home. The higher the CADR level to more powerful the air purifier.
